Add Filepicker to all folder selection text boxes

[mstrhakr]

Summary

Upgrade custom folder text box with filepicker support

Detailed description

Yes, its possible again to use a custom folder which is great, only thing is it would be awesome (but probably more work) to implement the default unraid filepicker, so i wont have to copy paste a folder, but can select the folder
